How are mid-ocean ridges created
WebThe Gakkel Ridge (formerly known as the Nansen Cordillera and Arctic Mid-Ocean Ridge) [1] is a mid-oceanic ridge, a divergent tectonic plate boundary between the North American Plate and the Eurasian Plate. [2] It is located in the Eurasian Basin of the Arctic Ocean, between Greenland and Siberia, and has a length of about 1,800 kilometers ... Web• When scientists measured the age of seafloor rocks, they found that younger rocks are closer to the mid-ocean ridges, and older rocks are found closer to trenches. These two pieces of evidence support the idea that the seafloor spreading is valid by showing that the seafloor is not all the same age and is constantly being created at mid ocean ridges …
